摘　要：

采用RT-PCR 方法检测茉莉酸(JA)/乙烯(ET)依赖性信号途径中关键基因PDF1.2 在转草酸氧化酶基因(OXO)油菜株系与未转化对照中的表达差异。结果表明, 在转基因油菜不同株系中PDF1.2都有不同程度的上调表达, 预示着转OXO油菜对菌核病的抗性增强可能与激活JA/ET依赖性信号途径有关

Abstract:

The expressions of PDF1.2, a key gene in the jasmonic acid (JA)/ethylene (ET)-dependent signaling pathway, were measured in oxalate oxidase (OXO) transgenic and non-transgenic oilseed rapes (Brassica napus) by RT-PCR. The results showed that the expression of PDF1.2 was up-regulated in different OXO transgenic oilseed rape lines, which indicated that the mechanism of disease resistance to Sclerotinia sclerotiorum was related to the induction of the JA/ET-dependent signaling pathway.

Key words: oilseed rape (Brassica napus); Sclerotinia sclerotiorum; PDF1.2
